Notes on use
Note 1: While using the spiral cover, keep a center receiver attached to each of the terminals. (The center receiver must be procured by the customer.)
Main dimensions of center receiver
D1 = D + (1 to 2 mm), d2 = d - (1 to 2 mm), d3 = D or more
The spiral cover involves rotation and changes in diameter when it expands and contracts. Thus, be sure to use the center receivers.
Note 2: If the working length is insufficient with one spiral cover, connect the small diameter side to the inside as shown in Figure 1.
Note 3: When using the vertically placed version, be sure to mount it so that the large diameter side will be at the top. (Figure 2)
Avoid connecting in the vertical direction because the spiral cover sinks due to its own weight, causing the operation to be unstable.
CAUTION
* The spiral cover of the delivered product is packed using a stop band in a compressed state. Because of strong spring pressure, it jumps out when the stop band is cut. Pay sufficient attention to its handling, for example, when incorporating it into the body.
